Dear all, Stictly following the updating prodecures, I was updating firmware from system V1.22 to 2.13 (wi-fi v1.02 to v2.00), and the device went frozen right after the process started, at PHASE 1 writing... [01/07]... After 10 hours with USB power source, there is no further process and no response... What should be the correct procedures to deal with the situation ? What will be consequences if power it off or take out the battery? Thank you very much in advance for your kind advice!!!! Kevin P.s. I am updating the firmware, due to an issue that the device totally freezes when the WIFI button is pressed. Hoped updating the firmware might help solve the problem.
